Ireland's army of Susan Boyle fans were today holding out hope that the Britain's Got Talent star would make the Irish shows on Tuesday June 30.

The hit TV show is on tour across Britain and Ireland but Boyle has missed several gigs ahead of Tuesday's show at the 02 arena in Dublin.

Up to 15,000 fans are expected to descend on the venue for the Irish leg of the tour.

Boyle, 48, shot to fame after her audition for the hit reality show but came a shock second at the show's finals in May.

She checked into the Priory, an exclusive clinic in London, where she was treated for exhaustion.

Since then she has failed to make several performances of the hit TV show tour and fans are concerned that the concert tour is taking too big a toll on the shy Scotswoman.

Boyle joined the first shows on the “Britain’s Got Talent” tour in Birmingham and Sheffield but failed to appear at subsequent shows in Manchester, Liverpool, Cardiff and Nottingham.

Talent judge Simon Cowell has admitted that they may have done too much too soon with Boyle.

"She was still tired," a rep said. "With all the traveling the decision was made to have a rest until Sunday."

In Dublin, SuBo fan Moira Hegarty, 47, said she had been lighting candles in her local church for Susan.

"There's something about Susan that really moved me," she said. "I cried my eyes out when I heard that first performance when she did the audition."

"I still can't believe she didn't win. That dance group was rubbish. I think there was something wrong with the voting."

Her friend, Catherine Hartnett, 46, agreed. "It doesn't make sense that Susan didn't win. She was so clearly the better performer, even on the night."

Both friends are attending the concert at the O2 arena and say they are only going to see Boyle.

"I don't care about the rest of the tour," said Hegarty. "I especially don't want to see Diversity."

But both Hartnett and Hegarty are concerned that the traveling and the touring might be just too much for Boyle.

"She's obviously under pressure," said Hartnett. "I hope she doesn't fall apart here, that would be awful."

However, Susan wowed the crowds in the South of England last night when she sang "I Dreamed a Dream," at a sell-out concert in Bournemouth.

This followed a stunning performance at London's Wembley Arena where fans were treated to "I Dreamed a Dream" and "Memory."

Just last night, thousands of fans screamed their way through the show which was dedicated to tragic superstar Michael Jackson.

The show featured stunning performances from all 10 finalists but the biggest cheers were kept for SuBo as she is affectionately known.

In Dublin, Hartnett and Hegarty joined thousands of fans who were hoping for more of the same from Boyle on Tuesday night.
